Effects of contextual diversity on semantic decision and reading aloud: evidence from a word learning study in English as a second language / Efectos de la diversidad contextual en la decisión semántica y la lectura en voz alta: evidencia de un estudio de aprendizaje de palabras en inglés como segundo idioma

This experiment investigated contextual diversity effects on novel word learning in English as a second language (L2). A group of advanced English speakers, whose native language was Spanish, participated in the study. Participants learned the meaning of real but obscure words that were embedded in either two or 12 different sentences and learned over two days (frequency of exposure was kept constant). On day three, participants were tested using reading aloud and semantic decision tasks. The results showed that participants learned the meaning of words in both conditions fairly well as revealed by their accuracy in the semantic decision task. However, words experienced in 12 different contexts generated more accurate and faster reaction times (RTs), suggesting the acquisition of more robust semantic representations. Strikingly, reading latencies were also faster for the 12-sentence condition, which might imply that semantics has an effect on reading newly learned words in English as a second language. These results are discussed and accommodated in view of the DRC and the PDP models of single-word reading.     

The Place of Purpose in Life in Women’s Positive Aging

Purpose in life is an orientation associated with energy, effectiveness, and optimism. A general trend is for purpose to decline in the later years, with unclear implications for positive aging. This article, however, takes a new approach to exploring the role of purpose. Using data from the Mills Study, a 55-year study of women’s adult development, we examine four sharp patterns of change in purpose on Ryff’s scale (1995 Ryff, C. D. (1995). Psychological well-being in adult life. Current Directions in Psychological Science, 4, 99–104. doi:10.1111/1467-8721.ep10772395[Crossref], [Web of Science ®] , [Google Scholar]) between ages 61 and 70: high at both times, low at both times, and changes from high to low or low to high. Guiding ideas are advanced about each kind of change and findings examined for each group. Looking at individual women's lives since childhood provides illustrative examples of each pattern. These lives show the impact of depression, inner resources, personality traits (especially Conscientiousness), attachment (secure and avoidant/dismissive styles), life situations (e.g., retirement), and events (e.g., early parental loss or widowhood), and of a motivation in one's 60s to grow or to transform regrets. Women differed in how traditional their lives were and in how much they associated purposiveness and goal attainment with life satisfaction. Implications for therapists include both helping women find the energy and commitment associated with purpose in life, and helping them value more process-oriented experiences such as appreciation, wonder, connection, and relationship. Emphasis on appreciation may become more common as women age. Positive aging is manifested in these ways, but also in acceptance and the courageous and steadfast coping with painful situations.     

Feature Statistics Modulate the Activation of Meaning During Spoken Word Processing

Understanding spoken words involves a rapid mapping from speech to conceptual representations. One distributed feature‐based conceptual account assumes that the statistical characteristics of concepts’ features—the number of concepts they occur in (distinctiveness/sharedness) and likelihood of co‐occurrence (correlational strength)—determine conceptual activation. To test these claims, we investigated the role of distinctiveness/sharedness and correlational strength in speech‐to‐meaning mapping, using a lexical decision task and computational simulations. Responses were faster for concepts with higher sharedness, suggesting that shared features are facilitatory in tasks like lexical decision that require access to them. Correlational strength facilitated responses for slower participants, suggesting a time‐sensitive co‐occurrence‐driven settling mechanism. The computational simulation showed similar effects, with early effects of shared features and later effects of correlational strength. These results support a general‐to‐specific account of conceptual processing, whereby early activation of shared features is followed by the gradual emergence of a specific target representation.     

Making Sense of Dynamic Systems: How Our Understanding of Stocks and Flows Depends on a Global Perspective

Stocks and flows (SF) are building blocks of dynamic systems: Stocks change through inflows and outflows, such as our bank balance changing with withdrawals and deposits, or atmospheric CO₂ with absorptions and emissions. However, people make systematic errors when trying to infer the behavior of dynamic systems, termed SF failure, whose cognitive explanations are yet unknown. We argue that SF failure appears when people focus on specific system elements (local processing), rather than on the system structure and gestalt (global processing). Using a standard SF task (n = 148), SF failure decreased by (a) a global as opposed to local task format; (b) individual global as opposed to local processing styles; and (c) global as opposed to local perceptual priming. These results converge toward local processing as an explanation for SF failure. We discuss theoretical and practical implications on the connections between the scope of attention and understanding of dynamic systems.     

Career Decision‐Making Self‐Efficacy Change in Italian High School Students

The authors explored the effects of a structured‐group career intervention among 280 Italian high school students. Hierarchical linear models indicated the intervention's effectiveness in increasing career decision‐making self‐efficacy and, consequently, career exploration, but not in decreasing career choice anxiety. In addition, partial confirmation was found for the moderating effects of participants' expectations and motivation to change on the relationship between career decision‐making self‐efficacy and career choice anxiety. The findings support the development of a systematic vocational guidance program in Italian schools.     

The Development and Testing of a New Version of the Cognitive Reflection Test Applying Item Response Theory (IRT)

The cognitive reflection test (CRT) is a short measure of a person's ability to resist intuitive response tendencies and to produce a normatively correct response, which is based on effortful reasoning. Although the CRT is a very popular measure, its psychometric properties have not been extensively investigated. A major limitation of the CRT is the difficulty of the items, which can lead to floor effects in populations other than highly educated adults. The present study aimed at investigating the psychometric properties of the CRT applying item response theory analyses (a two‐parameter logistic model) and at developing a new version of the scale (the CRT‐long), which is appropriate for participants with both lower and higher levels of cognitive reflection. The results demonstrated the good psychometric properties of the original, as well as the new scale. The validity of the new scale was also assessed by measuring correlations with various indicators of intelligence, numeracy, reasoning and decision‐making skills, and thinking dispositions. Moreover, we present evidence for the suitability of the new scale to be used with developmental samples. Finally, by comparing the performance of adolescents and young adults on the CRT and CRT‐long, we report the first investigation into the development of cognitive reflection.

Now or Later? Attentional Processing and Intertemporal Choice

The tendency to discount future prospects in lieu of smaller immediate outcomes is known as temporal discounting. The current work used eye‐tracking methodology to examine attentional processing to different elements of choice during an intertemporal decision task. Our findings reveal that those who tend to prefer the immediate option demonstrate attentional biases that were predictive of choice. When losses were at stake, selective attention biases also predicted unique variance in self‐report measures of risk taking, impulsivity, and self‐control beyond what was accounted for by a discounting parameter (k), a typical method for summarizing intertemporal choice data. Overall, our findings suggest that eye‐tracking measures of selective attention may allow for a better theoretical understanding of the mechanisms and processes involved in intertemporal choice.

How can individual differences in autobiographical memory distributions of older adults be explained?

The reminiscence bump phenomenon has frequently been reported for the recall of autobiographical memories. The present study complements previous research by examining individual differences in the distribution of word-cued autobiographical memories. More importantly, we introduce predictor variables that might account for individual differences in the mean (location) and the standard deviation (scale) of individual memory distributions. All variables were derived from different theoretical accounts for the reminiscence bump phenomenon. We used a mixed location-scale logitnormal model, to analyse the 4602 autobiographical memories reported by 118 older participants. Results show reliable individual differences in the location and the scale. After controlling for age and gender, individual proportions of first-time experiences and individual proportions of positive memories, as well as the ratings on Openness to new Experiences and Self-Concept Clarity accounted for 29% of individual differences in location and 42% of individual differences in scale of autobiographical memory distributions. Results dovetail with a life-story account for the reminiscence bump which integrates central components of previous accounts.     

The Curious Case of the De-ICD: Negotiating the Dynamics of Autonomy and Paternalism in Complex Clinical Relationships

This article discusses the response of our ethics consultation service to an exceptional request by a patient to have his implantable cardioverter defibrillator (ICD) removed. Despite assurances that the device had saved his life on at least two occasions, and cautions that without it he would almost certainly suffer a potentially lethal cardiac event within 2 years, the patient would not be swayed. Although the patient was judged to be competent, our protracted consultation process lasted more than 8 months as we consulted, argued with, and otherwise cajoled him to change his mind, all to no avail. Justifying our at times aggressive paternalistic intervention helped us to reflect on the nature of autonomy and the dynamics of the legal, moral, and personal relationships in the clinical decision-making process.     

A Broader Understanding of Moral Distress

On the traditional view, moral distress arises only in cases where an individual believes she knows the morally right thing to do but fails to perform that action due to various constraints. We seek to motivate a broader understanding of moral distress. We begin by presenting six types of distress that fall outside the bounds of the traditional definition and explaining why they should be recognized as forms of moral distress. We then propose and defend a new and more expansive definition of moral distress and examine how it can enable the development of a taxonomy of moral distress.
